Description

A child's enema device

technical field

The utility model relates to the technical field of medical enema, in particular to an enema device for children.

Background technique

Enema is a treatment method in which a catheter is inserted into the colon from the anus through the rectum to perfuse fluid to achieve ventilation and defecation. This method can stimulate peristalsis, soften and remove feces, and has the functions of physical cooling, induction of labor, dilution of intestinal toxins, and reduction of absorption. Enema is a commonly used clinical nursing technique and route of administration.

Some existing children's enema devices use pouring injection, that is, a funnel-shaped drug inlet is used, a hose is connected to the outlet, and the drug is poured into the funnel container. On the one hand, this method is unsanitary, and the drug will be in contact for a long time. The air carries more bacteria and other pollutants. On the other hand, due to the pressure relationship between the internal and external air in the intestinal tract, it is sometimes impossible to completely inject the medicine into the intestinal tract by relying on the natural pressure difference; most of the existing children The connection between the hose of the enema device and the drug delivery device is directly plugged. When the child resists and twists, it is easy to cause drug leakage, which increases the difficulty and complexity of medical treatment; many children's enema devices deliver drugs. There is a single type of hose. Due to the different diameters of the anus and intestines of children of different ages, a single type of drug delivery hose is not targeted. If the model is not matched, the medicine injected into the intestine will flow out from the anus or be too thick. It causes discomfort in children, increases resistance, and increases the difficulty of medical treatment.
